NSE vs BSE: Which Ticker Should You Use with the API?

India has two main stock exchanges, the NSE and the BSE, and most large companies are listed on both. When you call the API you pass a ticker symbol — here's how to get the right one.

Tickers are exchange symbols

Use the plain exchange symbol in uppercase — RELIANCE, TCS, INFY — not the .NS/.BO suffixes some other providers use. For a company listed on both exchanges, the plain ticker resolves to the NSE listing by convention.

When a ticker is shared by two companies

Occasionally the same symbol belongs to two different companies — one on NSE and a different one on BSE. In that case you can disambiguate with an exchange parameter to reach the specific listing you want.

Resolving a name to a ticker

If you only have a company name, call GET /v1/search with the name or a partial symbol — it returns the matching NSE/BSE tickers you then pass to every other endpoint. You can also browse the full universe on the stocks directory. See the search reference for details.
